One of the main drawbacks of E Ink ereaders is that there is no way to read your books without an additional light attachment. Reading at night, on a train, or in any other low-light situation will pretty much have you sunk unless you drop $20 for an accessory. Barnes & Noble has set out to solve this problem with the Nook Simple Touch with Glowlight. It's the same Nook Simple Touch you know and love, but now there's a row of soft glowing LED lights at the top of the screen, allowing you to read anytime, anywhere, and like Barnes & Noble says, it's "amazing in bed." Bedroom antics aside, it's an attractive addition to the already fetching device, and comes with a competitive price tag of $139.

Of course, adding light to the mix will inevitably drain your battery a lot faster than without. Good news is, you'll still get a month's worth of reading time with Glowlight turned on. Want one for yourself? You can preorder one today, and the Simple Touch with Glowlight will start shipping in early May. Perfect timing for Mother's Day, no?
